2 Claims.

This invention relates to adjustable guides for the paper plate of atypewriter and the general object is to provide means whereby a pair ofguides can be adjusted simultaneously by a movement of either guide.

Another object of the invention is to provide a scale to facilitate theadjustment of the guide.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure l is a front view of the paper plate showing the inventionthereon.

Figure 2 is a rear view thereof.

Figure 3 is a vertical sectional view through Figure 1.

Figure 4 is a blank from which one of the bracket members is formed.

Figure 5 is a view of the bracket member after the blank has beenformed.

Figure 6 is an edge view of the bracket member.

In these drawings the paper plate or platform of a typewriter is shownat A and the guide supporting rod is shown at B. In carrying out myinvention I find a pair of guides C each of which is provided with ahook shaped upper part 1 terminating in rear of the plate in a ring oreye 2 through which the rod B passes. A bracket member D is associatedwith each guide and is preferably formed of a T- shaped blank 3 havingthe holes 4 in its stem part and the large hole 5 adjacent each end ofits head part with a small projection 6 extending into each hole 5. Thisblank is bent as shown in Figures 5 and 6 so that the end portions ofthe head part are bent parallel to each other and at right angles to themiddle portion of the head 5 and this head part is so bent to form thespace for receiving the eye 2 of each guide. The projections 6 engagethe usual groove 7 in the rod B for preventing rotary movement of thebracket members. A pair of pulleys 8 are rotatably connected to theunder side of the plate A as shown in Figure 2 and a flexible member orcable 9 passes over the pulley and has its end connected to the turnbuckle 10. One of the bracket members is connected to the upper reach ofthe cable by a screw 11 and the other bracket member is connected to thelower reach by a similar screw 12. These screws engage one of the holes4 and by providing two holes in each bracket member they can be formedby the same punch or press and need not be made left hand and righthand.

Thus it will be seen that when one of the guides is adjusted in eitherdirection the other guide will be similarly adjusted in an oppositedirection. Thus when the guides are to be adjusted it is simplynecessary to grasp one guide and move it in the desired direction and asthis guide is being moved, the other guide is moved in an oppositedirection by the endless member 9.

A scale strip 13 is fastened at the front of the plate for facilitatingadjustment of the guide and the graduations on this plate can bearranged to suit the type of the typewriter on which the device is used.

If desired the bracket members may be made in one part with the paperguides.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts provided thatsuch changes fall within the scope of the appended claims.

Having thus described my invention, what I claim as new is:

1. In combination with the paper plate or platform of a typewriter andits guide supporting bar, a pair of guides extending over the front ofthe plate and having parts slidably arranged on the bar and means foradjusting one guide simultaneously as the other guide is being adjusted,said means comprising an endless member, pulleys for supporting theendless member, means for connecting one guide to the upper reach ofsaid endless member and means for connecting the other guide to thelower reach thereof.

2. In combination with the paper plate or platform of a typewriter andits guide supporting bar, a pair of guides extending over the front ofthe plate and having parts slidably arranged on the bar and means foradjusting one guide simultaneouly as the other guide is being adjusted,said means comprising an endless member, pulleys for supporting theendless member, means for connecting one guide to the upper reach ofsaid endless member and means for connecting the other guide to thelower reach thereof, and a graduated strip on the front face of theplate and located under the guide for facilitating. adjustment thereof.
